### {% linkable_title Usage of templating in `command:` %}
[Templates](/docs/configuration/templating/) are supported in the `command:` configuration variable. This could be used if you want to include the state of a specific sensor as an argument to your external script.
```yaml
# Example configuration.yaml entry
sensor:
- platform: command_line
name: wind direction
command: 'sh /home/pi/.homeassistant/scripts/wind_direction.sh {{ states.sensor.wind_direction.state }}'
unit_of_measurement: "Direction"
```
